Mayhems fluids now available

We are happy to announce that WATERCOOL now cooperates with Mayhems Solutions Ltd! We carry Mayhems Tubing since quite a while, but starting today, we now also offer Mayhems cooling fluids! With 15 years of experience in the development and production of cooling fluids for PC liquid cooling setups, Mayhems has set industry standards multiple times. We now carry the Mayhems X1 line: translucent fluids in different colors that come with all relevant additives like corrosion inhibitors for copper, brass, steel, nickel and aluminum and biocides against algae and bacterial growth included.

WATERCOOL passes tax savings on to customers

Since July 1st, the German value added tax (VAT) is reduced from 19 to 16 percent. Of course, we pass this saving on to our customers! All previous orders that haven't shipped yet will also be invoiced under the reduced VAT and we will refund the overpayment after shipping.

We are currently experiencing some display errors in our shop where partially, prices are still displayed with the old VAT value. We are working with the software provider to solve these display errors as fast as possible.


VAT is only applied to orders from customers within the EU. If your shipping address is outside of the EU, German VAT doesn't apply to you, so there will be no price change, at all.


Product development survey: pump tops

We are currently planning a complete overhaul of our pump tops. We want to refresh, expand, and homogenize the lineup, make the parts compatible with each other, and give it a new, modern design. We already have many criteria fixed internally - but on some questions, we are completely open for input. So we want to ask you, our customers and users, for your opinions on these issues: what do you expect from a new pump top? This survey has 8 questions and takes less than 5 minutes to complete.
Please help us developing the perfect product for YOU!

Shipping restrictions with DHL and FedEx

Production and Assembly at WATERCOOL still operate normally. But our shipping partners Deutsche Post, DHL and FedEx report different restrictions. There are some countries or regions that are currently not supported by some or all of the shipping companies due to the Corona pandemic. As the status changes dynamically, we will not provide a static list of restricted regions here, but ask you to check the respective statements:

If you currently have an open order with us that is affected by the shipping restricions, please contact so we can find an individual solution for your situation.
Stay healthy!

WATERCOOL not influenced by Corona pandemic

The Corona pandemic is currently shaking the whole world. But while the systemic impacts are pretty drastic, the individual effects can be close to not noticeable. Thanks to WATERCOOL's slim structures and the location, we are well prepared for the current situation. Production, assembly and shipping continue without any restraints! We still offer full service to all our customers and ship all of our popular HEATKILLER® components.
Of course, we watch the developments closely and follow all cautionary measurements by the authorities. We use remote work (Home Office) for all roles applicable, and follow strict hygiene protocol in all roles that physically interact with the product, so that the customers receive a clean and safe product!

Forum deactivated

Our forum's software became incompatible with our general homepage system due to a software update. As we are currently working on a completely new homepage, we decided to shut the forum down for now. The new homepage will have a dedicated helpdesk area with a ticketing system and other feedback channels.
Of course, we are still accessible and looking forward to help our customers: we usually answer all requests via our contact form and direct mails to within 24 hours.

HEATKILLER® IV PRO for Threadripper™ compatible with sTRX4

AMD introduced a new socket for their third gen of Threadripper™ processors: sTRX4. To make full use of these 24- or 32-core CPUs, one needs a potent cooling solution. Our HEATKILLER® IV PRO for Threadripper™ water blocks are the perfect match: the blocks are both compatible with TR4 and sTRX4 and can adequately cool all Threadripper™ and Epyc™ CPUs!
Several independent tests have confirmed that the HEATKILLER® IV PRO for Threadripper™ is the best performing block on the market: already last year, we won the gold award in XtremeRigs CPU block roundup. And since a couple of days, we can also claim the bestranking gold award in the new comparative test by Hardware-Helden!
